FIRST SORROWFULL MYSTERY: Agony in the Garden.
At Gethsemane Jesus prays as He contemplates the sins of the world.

Then cometh Jesus with them unto a place called Gethsemane, and saith unto the disciples, Sit ye here, while I go and pray yonder. And he took with him Peter and the two sons of Zebedee, and began to be sorrowful and very heavy. Then saith he unto them: "My soul is exceeding sorrowful, even unto death: tarry ye here, and watch with me". And he went a little farther, and fell on his face, and prayed, saying: "O my Father, if it be possible, let this cup pass from me: nevertheless not as I will, but as thou wilt". (Mat 26,36-39). And being in an agony he prayed more earnestly: and his sweat was as it were great drops of blood falling down to the ground. (Luk 22,44)
